在双代号网络进度计划的时间参数中，下列公式正确的是（）A、TFi-j＝LSi-j－LFi-jB、TFi-j＝ESi-j－EFi-jC、TFi-j＝LSi-j－EFi-jD、TFi-j＝LSi-j－ESi-j
A customer has an x445 and uses the internal LSI adapter to manage two 146GB drives in the chassis. The customer is noticing performance issues when deploying a database with significant write activity on the internal drives. Should they consider using a ServeRAID-6M with 256MB of cache instead， and why or why not？（）A、Yes， the internal LSI SCSI adapter has no write cache.B、Yes， the internal LSI SCSI adapter is unreliable.C、No， the downtime to install the card and reformat the drives would be cost prohibitive.D、No， there will be no performance benefit， because drive performance is the bottleneck.
